timeout, LDAPMessage
result);
int ldap_msgfree(LDAPMessage
msg);
The ldap_result routine will block or not, depending upon the setting of the timeout parameter. If timeout is not a NULL pointer, it specifies a maximum interval to wait for the selection to complete. If timeout is a NULL pointer, the select blocks indefinitely. To effect a poll, the timeout argument should be a non-NULL pointer, pointing to a zero-valued timeval structure.
If the result of a specific operation is required, msgid should be set to the invocation identifier returned when the operation was initiated, otherwise LDAP_RES_ANY should be supplied. The all parameter only has meaning for search responses and is used to select whether a single entry of the search response should be returned, or all results of the search should be returned.
A search response is made up of zero or more search entries followed by a search result. If all is set to 0, search entries will be returned one at a time as they come in, via separate calls to ldap_result. If it is set to 1, the search response will only be returned in its entirety, that is, after all entries and the final search result have been received.
Upon success, the type of the result received is returned and the result parameter will contain the result of the operation. This result should be passed to the LDAP parsing routines, as documented on the ldap_first_entry(3ldap) manual page, for interpretation.
The possible result types returned are:
#define LDAP_RES_BIND 0x61L #define LDAP_RES_SEARCH_ENTRY 0x64L #define LDAP_RES_SEARCH_RESULT 0x65L #define LDAP_RES_MODIFY 0x67L #define LDAP_RES_ADD 0x69L #define LDAP_RES_DELETE 0x6bL #define LDAP_RES_MODRDN 0x6dL #define LDAP_RES_COMPARE 0x6fLThe ldap_msgfree routine is used to free the memory allocated for a result by ldap_result or by the routines documented on the ldap_search_s(3ldap) manual page. It takes a pointer to the result to be freed and returns the type of the message it freed.
